Aluminum Polishing Sheet is a special Aluminum Sheet.Its surface has been polished hence gives good performance in surface condition.The advantage of aluminum sheet is as follows:
1. Easy to process.

Leaf area index refers to the leaf area index, also known as the leaf area coefficient, is the ratio of the total area of ​​a crop leaf on the ground to the floor space. Namely: leaf area index = total area of ​​green leaves/footprint. The leaf area index is a good dynamic indicator that reflects the size of the crop population.
Within a certain range, the crop yield increases with the leaf area index. It can be seen that the size of the leaf area index is related to the yield of the crop, and the leaf area is a part of the molecule in the calculation formula of the leaf area index. The total area of ​​the blades is obtained by accumulating the surface of each blade of a piece of land. Therefore, leaf area is a manifestation of crop yield. The size of the leaf area is related to the photosynthesis efficiency of the leaf, and photosynthesis is the process of accumulating organic matter. Therefore, the size of the leaf area is related to photosynthesis.
Therefore, in agriculture, we often use the living leaf area meter to determine the area. The living leaf area meter can be carried directly on the hand and brought to the field. When measuring the area of ​​the leaf, only the leaves need to be clamped, and then the leaf can be slowly stretched to obtain the length and width of the leaf and the area of ​​the leaf. This leaf area is determined. The greatest advantage of the instrument is its ability to achieve a non-destructive determination of the leaf area, which plays an important role in guiding production. Continuous monitoring can understand the growth trend of the crops and guide the farmers to rationally apply fertilizer to the crops.
The results show that the casting aluminum alloy with good casting property or deformation aluminum alloy with good processing plasticity can be obtained by adding certain Ba Au Du element.
2. Good conductivity and thermal conductivity.
The electrical and thermal conductivity of aluminum is second only to silver, copper and gold.
3. The density is small.
The density of aluminum and aluminum alloy is close to 2.7 g / about 1 / 3 of that of iron or copper.
4. High strength.
The strength of aluminum and aluminum alloy is high. The matrix strength can be strengthened by cold working to a certain extent, and some brands of aluminum alloy can also be strengthened by heat treatment.
5. Good corrosion resistance.
The surface of aluminum is easy to produce a dense and firm protective film of Al2O3, which can protect the substrate from corrosion.
The role of living leaf area meter in conservation tillage
One of the main technical aspects of sustainable agricultural development is conservation tillage. Mainly through the implementation of no-tillage and ploughing the farmland to cover the field, to control the soil wind erosion pollution, in order to improve the soil fertility and drought resistance and water saving capacity. In the conservation tillage process, a variety of instruments are applied to ensure the healthy growth of the crop. Among them, the living leaf area meter is one of the instrument configuration lists.
